PERMABOND® 102 is a low viscosity general purpose cyanoacrylate adhesive suitable for bonding close-fitting components. It is fast setting and suitable for use on plastics, rubber and metals. Cyanoacrylate adhesives are single component adhesives that polymerize rapidly when pressed into a thin film between parts. The moisture adsorbed on the surface initiates the curing of the adhesive. Strong bonds are developed extremely fast and on a great variety of materials. These properties make PERMABOND cyanoacrylates ideal adhesives for high speed production lines.
FEATURES:
- Plastic and rubber bonding
- Applications requiring fast fixturing
- Ease of use – no mixing or heat cure
- Bonds most materials
- 100% reactive, no solvents
APPLICATIONS:
- Bonding close-fitting components
- Plastic, rubber, metals
